Abstract

1361638 Pressure sensitive copy sheet WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd 6 Sept 1972 [23 Sept 1971 20 Jan 1972] 44474/71 and 2785/72 Heading D2B A pressure sensitive copy sheet for use in systems of both the single sheet and transfer type comprises a base carrying a coating of microcapsules containing an organic, initially colourless, colour former dissolved in a solvent which includes one or more dibenzyl benzenes of formula: wherein R 1 to R 6 each represent hydrogen, C 1-4 alkyl or a C 7-8 alkaryl radical. The solvent may be diluted with kerosene and the colour former may be crystal violet lactone, benzoyl leuco methylene blue, a 3, 3-bis (dialkyl indolyl) phthalide, a 3-dialkylamino-6-alkyl-7-alkylaminofluorane or a 3-dialkylamino-7-dialkylamino fluorane.
